Waterproofing of Exposed Surfaces and Facades while maintaining its beauty

Customer main focus is the beautification done to the construction whereas, from the contractor’s point of view, it’s a must to protect and preserve the structure for the long term. A contractor faces a problem over this concern when a waterproofing treatment is to be done on an exposed brick or façade surface.

Nowadays, there is a humungous demand for an exposed brick look on the outer surface of the construction. Also, stone tiling and façades are getting very common in the middle-eastern market. These surfaces are very vulnerable to water seeping and can lead to structural damage and seepages. The main concern for a contractor is to provide waterproofing in these conditions without spoiling the beauty of the exposed brick texture on the stone façade finish. To resolve this Zydex industries provide a penetrative nanotechnology solution that forms a chemical bond with the surface. This solution penetrates the exposed brick/stone façade surface and treats them to make them water repelling in nature. The product is 100% silane called Zycosil+ which reacts with the structure surface and forms a chemical bond and does not get affected by temperature or climate change. Zycosil+ application slows down the cracking of the structure and makes the whole surface hydrophobic i.e. water repelling in nature. Zycosil+ also takes care of other problems like leakages, seepages, peel-off, efflorescence, and further structural damage. It also provides UV, Heat, and Abrasion stability and safe to apply indoors. The application is simple and does not require trained labour. The solution can be sprayed, brushed, or flooded after mixing with water and has a large coverage area. The best part of this solution is that the waterproofing chemical solution provided by Zydex is transparent and does not hinder the beauty of the exposed brick texture or the stone façade. This application of Zycosil+ solution on the exposed surface enhances the durability of the structure and solves the problems of the contractor and the owner. Nowadays, contractors and owners prefer waterproofing for the construction work to protect the buildings from leakage, seepage and avoid further complications.

Zydex waterproofing solution is applicable for both the exterior and the interior surface.
Hence, the Zydex waterproofing solution provides a complete solution for protecting the exposed structure.

The challenges of Fixing Large Size Stones/Tiles on Façades

Beautification of building/structure is an expensive project. Owners usually spend a lot of money on maintaining it for a longer duration. A major section of this beautification process is fixing large size Stones /Tiles which play a critical role in the aesthetics of the structure.

Fixing these large size Stone and Tiles are pretty easy on a horizontal surface. But this gets tricky when done on a vertical surface especially when the requirement is to keep it fixed for longer time. The heavy weight of these stones/tiles are a challenge for contractors. These Stone and Tiles pieces are very large and weigh a lot which causes gravity to play its part and results in de-bonding. To hold that much weight on the vertical surface, the contractor only has the support of one side. Too much vertical pressure on the attached side causes Stone/Tiles to fall from the facade. The major reason for this is the formation of polylithic surface /structure and resulting in non-monolithic strength. This leads to cold joints. These joints are the main cause of failures leading to Stone/Tiles falling off the facade. This is a major challenge for the contractors and the only solutions available are either to cut the Stones/Tiles into smaller pieces and then attach or use expensive solutions to fix them. These are not a viable option for customers who are looking for a cost-efficient solution without compromising on the aesthetics of these stones or tiles.

To solve this problem, Zydex introduces an innovative product ZycoFix Ultra that can tackle the problems of contractors by fixing the large-sized, porous Stone/Tiles. ZycoFix can be applied on the surface easily in order to get the monolithic strength and prevents the Tiles/stones from falling. These solutions are user friendly and easy to use and can be applied just by using a brush. ZycoFix, does not require any extra machinery. These applications do not demand skilled labour. Hence, the requirement of clients for beautification using large size Stone/Tiles can easily and economically be met by the contractors using Zydex Zycofix Ultra applied as per Zydex specifications.

Benefits of Using Asphalt for Paving

Asphalt is a mixture of aggregates, bitumen and filler, used for constructing and maintaining roads, parking areas, ports and airport runways among others.

There are various benefits to using asphalt for paving:

1. Smoothness / Ride Quality

Asphalt mixes provide a smoother pavement surface, thus reducing damages to the surface. It improves fuel efficiency and reduces wear & tear of the vehicle tyres. Finally, paving roads and highways with asphalt significantly reduces the noise generated by the tire/pavement interface providing for a quieter ride experience for the motorist.

2. Faster Construction

Asphalt roads can be constructed quickly. Traffic can be opened on the road after construction pretty quickly. Asphalt is ready for traffic right after it is compacted and cooled, which means better traffic flow, minimized closures and happier motorists.

3. Quick Maintenance

Asphalt pavements have the ability to last forever when designed properly. Using asphalt, the maintenance can be done quickly and at times, it can be done even with partially-open traffic. The road needn’t be blocked for a long time. Additionally, maintenance activities can be planned during weekends or off-traffic hours causing minimal disruption to commerce.

4. Safety

Road paved with asphalt mixtures will have a feature that it gets smooth like finish. It offers drivers skid resistance, splash back and better visual distinction between road markings.

5. Sustainability through Recycling

Asphalt is a recyclable material, meaning its lifecycle never ends. Once laid mixture can be dug up and re-used in the future for maintenance works or for new construction. This allows to preserve the environment by reducing the strain on the ecosystem, thereby driving the factor of sustainability in road construction.

However, it is not without its own disadvantages. Some of them are detailed below:

1. In order for asphalt to be used, the bitumen needs to be heated to 160 – 1800C so that it becomes a liquid which is fluid enough to be coated on the aggregates. This requires specialised training and experience to ensure that the activity runs smoothly.
2. Bitumen is a petroleum product, which releases hydrocarbons during its extraction. This causes serious environmental degradation. High heating temperatures also causes various environmental pollution.
3. Various heavy machinery is needed to construct asphalt pavements, even for small road construction. These types of equipments are expensive and requires skilled labour to operate.
4. Improper construction practices / negligence causes pavement to develop cracks and other kinds of deterioration. Extreme care is required for such practices.

Hot Mix Asphalt Vs Warm Mix Asphalt

The main difference between hot mix asphalt and warm mix asphalt is how they’re made.

Hot mix asphalt (HMA) is heated up to around 300 degrees Fahrenheit in a special oven to help reduce the curing time on the road. Warm mix asphalt (WMA) uses a process called “adhesive bonding” to create an even, strong bond between the aggregate and binder that allows it to be put down at about 180 degrees Fahrenheit without cooling.

HMA is produced and transported at a higher cost than WMA because of the higher temperatures needed to prevent it from solidifying.

Warm mix asphalt is more environmentally friendly than hot mix because it uses less fuel. The typical amount of fuel used to produce 1 ton of hot mix asphalt is 8 gallons, while with warm mix only 3.2 gallons is needed. Fuel consumption during WMA manufacturing is typically reduced by 20%.It also has a lower carbon footprint than hot mix, which means that not as much carbon dioxide is released into the air during production.

The reason warm mix asphalt can be placed at a lower temperature is because it is less viscous or thick than hot mix asphalt and therefore easier to apply at a lower temperature.

Construction crews can pave at lower temperatures, which allows to open the pavement for traffic sooner and lessens traffic gridlocks. The window for paving is widened and this results in the extension of the paving season, especially in colder climatic geographies.

On certain days when the air quality is bad, paving activities are halted, thereby delaying the process of paving. WMA also produces lesser emissions, making it a possibility to construct pavements on such non-attainment days. Also, working conditions are a lot better with WMA. Both at the production plant and on the building site, crews inhale lesser smoke and dust. This decrease is especially significant in tunnels where ventilation is lesser.

It has been utilized effectively in a wide scope of pavements with varying thicknesses. It is sufficiently strong to withstand high traffic demands. Warm Mix Asphalt has been utilized in a wide range of asphalt layers: dense-graded, stone matrix, porous, and mastic asphalt. Numerous WMA advances are available in the market, so the decision on the type of WMA can be adjusted according to the temperatures and materials required.

WMA has been utilized effectively in Europe for over 10 years. In the United States, WMA projects are presently in excess of 40 States.

4 ways for Road Dust Control

Paved roads are preferred because of its numerous benefits such as smoother rides and longer life. However, converting an unpaved road to a paved road involves huge costs, due to which efforts are made to maintain the condition of the unpaved roads, especially in areas with low traffic.

The unpaved roads (or Gravel Roads) cause air pollution and significant dust generation which hampers the quality of plant and human life in the region. Dust settlement on plants refracts the sunlight and reduces the efficiency of photosynthesis, causing growth inhibition. It also causes breathing and related troubles in humans. Also, dusty roads can cause damage to vehicles and dusty driveways will cause vehicles to require more frequent car-washings at the very least. So it is essential to reduce the dust generation by bonding them in place with the road surface.

Traditionally, spraying water on the surface periodically was considered to be a good solution for dust mitigation. However, in areas with dry climate, it will only be a temporary solution. Applying a salt solution offers another way. It captures the water from the atmosphere, keeps the road top surface damp and prevents it from turning into dust.
One widely accepted practice is to use Gravel. However, it may not be a long term solution as it needs to be anchored to the road below, causing a rough ride.

Chemical technologies such as Zycobond offer a more permanent solution for dust suppression. It facilitates strong chemical bonding between the soil particles and prevents captures existing & new fines, thereby reducing the number of watering cycles.

Dust Control Techniques for Low Volume Roads

Low Volume Roads comprise of more than 50% of the total road network. They generally serve as access-ways, with majority of the developing nations using it for commercial transportation of people and goods. With these low volume roads, come the dust and the need to reduce/eliminate them.
Controlling the dust is a vital factor towards health and safety of the people. It is also one of the largest contributor to air pollution. Generally accepted methods and techniques to control dust on these roads are:

1. Reducing the number and Traffic
Fast moving vehicles will stir up dust. Reducing the number of vehicles as well as the speed of the plying motors can help reduce the amount of dust significantly.

2.Gravel Spreading
Spreading a layer of gravel in top of the dusty surface will prevent the dust generation. However, due to the lack of bonding between the gravel and the soil particles, the gravel will move from place causing a bumpy ride to motorists. Also, the heavy load from the vehicles might push the gravel into the soil, especially if the road surface do not have enough fines.

3. Bind Soil Particles.
Another kind of dust palliatives includes chemicals which bind fine particles together or onto larger particles. Dust control products like Zycobond are used to bind the particles in place.

4. Sealing with Pavements
Constructing an asphalt pavement on top of the dusty surfaces are a good way to ensure dust control and facilitate faster and smoother movement of people & goods. With the advantages of asphalt pavements, it is a reasonable alternative for adoption.

5.Windbreakers
Windbreaks are barriers designed to slow the speed and redirect the flow of wind. Good windbreaks will not create excessive turbulence or wind eddies. Windbreak materials may include picket and board fences. Windbreaks are most useful when designed for specific wind directions.

6.Vegetation
Growing vegetation along the road sides is a good dust control measure. Plants not only cover the ground, preventing the dust from blowing away, but also holds the soil particles together by means of its roots.

7.Other Measures
Other alternatives including spraying calcium chloride and magnesium chloride mixed in water. Sometimes, bitumen emulsions are also used, by spraying over the existing dusty surface, which creates a layer on top of the soil particles, making them heavy enough to prevent being blown away.

Zydex dust control technology provides a solution to a number of problems be it the visibility issues, health problems or deterioration of the quality of roads.

Sustainable Road Construction

Sustainability focusses on meeting the needs of today, without compromising the needs of the future generations. The concept of sustainability focusses on the pillars of people, planet and profits. Transportation sector being one of the highest contributor to greenhouse gases, with the burning of fossil fuels during construction as well as the emissions from vehicles, faces a grave challenge of adopting sustainable practices to reduce the emissions during production, construction and maintenance.

Road construction consumes high quantities of energy at different stages of asphalt mix production & transportation, and during the excavation of materials for maintenance. The production of Hot Mix Asphalt used for paving, requires high temperatures of 150- 1800C making it a very high energy consuming sector, which in turn generates higher quantities of CO2. Engineers have been looking for solutions to reduce the emissions during production and construction, which later paved the way to low temperature asphalt mix production, also known as Warm Mix Asphalt. The production and paving of Warm Mix Asphalt offers huge benefits in terms of lesser emissions & fumes, longer hauling, and better working conditions, without compromising on the quality of the construction.

A wide range of solutions such as silane based chemicals, geogrids & reinforcements, bitumen additives etc. are being adopted for various activities such as soil stabilization, asphalt mix production and even for maintenance treatments such as microsurfacing, to reduce the environmental impact of road construction, thereby allowing the sector to take a step towards sustainability.

Other options include the use of recycled materials from existing pavements and shingles to reduce energy consumption. Bio-binders originating from natural resources is another alternative that have been gaining traction in the road construction sector, because of their myriad benefits with the added advantage of being biodegradable.

The future of sustainable road construction & maintenance practices not only depends on the use of new and improved material technologies, but also on other innovative initiatives & concepts such as:

1. Solar/Wind powered lights
2. Piezoelectric energy generations from vibrations of vehicles
3. Use of de-icers on the road surface
4. Glow-in-the-dark road markings
5. Electric & Autonomous Vehicles.

The rise of these technologies and practices aimed at reducing the environmental impact of the transportation sector pushes for the need to reduce the carbon footprint of the existing construction practices. The future of road construction is definitely moving towards a more sustainable approach as evident from the various potentially interesting initiatives that strives to reduce the ecological footprint of the existing road construction practices.

Why do roads get damaged frequently? Know the important factors

A pavement structure is designed and constructed to meet its service life, by taking into consideration the magnitude of the load and the environmental conditions under which it will have to sustain. However, along its service life, the pavement undergoes damage due to a multitude of factors. These factors can be classified as follows:

1. Climatic Conditions

The performance of road depends greatly on the temperature variations (wet and dry/freeze and thaw cycles), rainfall and moisture ingress. The materials used in road construction reacts differently with the presence of these factors. The variation of these factors beyond the tolerable limits will lead to premature failures of the roads. Common failures resulting from climatic variations are swelling and shrinkage of road layers, thermal cracks, potholes, stripping, debonding, bleeding and raveling. Generally, bitumen additives are used to help the pavement withstand these issues. Technologies such as adhesion promoters / antistripping agents prevent the moisture ingress into the asphalt mixes, keeping the pavement in a good condition.

2. Traffic Loading

The traffic load on any road is a very important criteria that determines the performance and ultimately the life of the road. All roads are designed for a given traffic/loading that it is likely to carry over its design life. Any significant overloading will affect the road performance and reduce the service life of the pavement. Few common failures resulting from excessive loading are shoving, rutting, fatigue cracking and depressions. These pavement distresses/failures can be avoided by designing the road adequately for future traffic and also with the use of high performance materials and technologies available. Chemical soil stabilization is one of the techniques that help the pavement withstand higher loads, by enabling to construct stronger soil bases. Other techniques also include, use of geogrids and geotextiles, fibres and modified bitumen binders, to provide higher strength and durability.

3. Operational Factors (Material Reliability and Construction Practices)

These factors includes everything from the usage of unusable/unsuitable materials to operational inefficiency in the field conditions. Inadequate practices lead to structural failures, roughness, cracks and moisture ingress in to roads and ultimately lead to pavement disintegration. Failure to obtain proper compaction, improper moisture conditions at the time of construction and inaccurate layer thicknesses after compaction all directly affect the pavement performance. The adoption of best and reliable construction practices will ensure the construction of durable and long lasting roads.

Consult Zydex and avoid premature failure of your road assets.

Need for Terrace & Roof Waterproofing

Waterproofing of a structure is essential for keeping the structure’s biggest enemy i.e. water from entering. Waterproofing of the terrace/roof is very essential especially in high rainfall areas. We must understand that waterproofing of a project is just 1% of the whole cost but takes care of the 90% of the problems that may damage the building.
The main use of waterproofing of the terrace/roof is to prevent the entering of water into the foundation, roof, walls, basements, buildings and other structures. These are done using waterproofing membranes which are either made of plastic, rubber, coated fabric materials or asphalt sheets.
Application of these waterproofing membranes can be a very time taking and tedious job and requires skilled labour. Any failure in them can lead to failure of the whole treated area. These membranes tend to get rigid & brittle leading to crack within 1-2 years because of the continuous/heavy load.
Zydex provides a solution which is in the form of an elastomeric membrane, Elastobar, which expands up to 250%. This membrane creates a homogeneous layer on the surface which prevents any cracks or pores formation due to joints. The membrane is water resistant, UV stable, highly stretchable and have high bonding strength hence when exposed to weather and continuous load, it does not brittle and break. Application of Elastobar is also very easy, user friendly, less time consuming and no extra source of heat is required. It can be done at any location and do not require skilled labour.
Hence, using Elastobar will continuous protection especially to heavy loaded and exposed areas like terrace/roof.

How is Zytonic M better than other bio-fertilizers and how is it beneficial for farmers?

Agricultural soils today need to produce safe, nutritious and affordable food for all. The world is concerned about deteriorating soil health due to the heavy usage of chemical fertilizers and crop-care chemicals. Moreover, reducing the impact of farming on the environment, human health and well-being of livestock, along with sustainably increasing farmer income, is where the real challenge lies.

Zydex has developed a next generation technology for soil fertility improvement that substantially boosts the natural soil biological population and its functioning efficiency. The Zytonictechnology platformenables bio-farming with reduced chemical inputs and substantial water savings, resulting in higher yields and improved crop quality.

1. Higher Germination:Zytonic M makes soils soft, porous, aerated and improves soil water-holding capacity, thereby improving germination from 70 to75% to 85 to 95%. It ensures 15 to 20% higher plant survival. Higher land occupancy per acre leads to 15 to 20% higher production.

2. Enhanced Plant growth & Quality: Soft and porous soils promote a larger, profuse white root zone with an extended mycorrhiza hyphae network. This along with the enhanced soil biology delivers substantially higher amount of nutrients and also makes them continuously available to the plants throughout the growing season. This results in each plant having a thicker stem, denser canopy and a 15 to 20% increase in flowering & fruiting. A large and biologically active root zone with optimum water, ensures higher nutrient density in the produce. This enhances the aroma, taste and shelf life of the agricultural produce, giving farmers a higher price realization for their farm produce.

3. Water Harvesting & Savings:Zytonic-M ensures that porous soils hold moisture even during drought-like conditions. At the same time, due to the higher infiltration capacity of the soil it allows excess rains to percolate down into the fields easily without flooding. This protects the crop from damage due to anaerobic conditions. Porosity improvement also helps to reduce the salt concentration in the topsoil. Higher infiltration rate means improved rainwater harvesting. Typically, 150-200 thousand liters of water can be recharged every year in ZytonicM fields. The moisture holding capacity improvement in Zytonic M fields also helps to extend the irrigation cycle by 30-40%.

4. Reduced usage of Chemical fertilizers & Pesticide Sprays: Only 20-25% of chemical fertilizers applied are actually utilized by plants. Zytonic-M improves the nutrient uptake capacity of the crops due to a larger and denser root zone with an extended mycorrhiza hyphae network. This ensures a 50% reduction in the need for chemical fertilizers and subsequently lesser irrigation requirement for plant growth. These 2 factors dramatically improve the crops immunity and resistance to pests and fungal attacks leading to a reduction in the number of chemical sprays required.

5. Improved Soil Health & Organic Carbon: The Zytonic-M treated fields have darker green foliage leading to enhanced photosynthetic activity. The higher sugar and carbohydrate production is pushed out as liquid root exudates to feed the enhanced soil biology. This along with remnants from a large root zone builds up soil carbon content, thereby improving soil health.
